For new energy vehicles, the most concerned thing users are the battery. On the one hand, they pay attention to battery safety and do not catch fire and spontaneous combustion at any time. On the other hand, I am worried about the service life of the battery. Because it is the same as the battery on our mobile phones, as the use time increases, the health of the battery will decline to a certain extent.
To give a simple example, suppose you are driving 100 kilometers when you first bought a new car, and you may be fully charged in 5 years, so you can only run 80 kilometers.
So in order to solve this problem, many car manufacturers have launched battery swap mode, such as NIO . The battery will not work then, and you can revive it with full health.
But most car brands will not do this, why? Because they feel that the attenuation of the battery is far lower than the service life of the entire vehicle!
Recently on the German YouTube channel "Out of Spec Reviews" Kyle Conner revealed the health of the battery based on his experience driving 200,000 miles (about 320,000 kilometers).
video Model X, about 65-80% of its total mileage uses Tesla 's dedicated supercharger or fast charging facilities. After driving 200,000 miles (about 320,000 kilometers), the battery capacity has been reduced by only 8.3 kWh. The new Model X P100D has a battery capacity of 93.7 kWh. After driving 200,000 miles (about 320,000 kilometers), the measured battery capacity remained at around 85.4 kilowatt-hours, with about 9.8% of the battery deteriorating.
The user explained that the Model X, which traveled 200,000 miles (about 320,000 kilometers), had no significant difference in acceleration even when traveling at the highest speed on the highway compared to the new car. In addition, except for the slight corrosion outside the car, water leakage in the trunk, peeling of the steering wheel leather, there are no other major problems, and the durability is quite high.
According to a report released last year, Tesla's battery is designed to retain 90% of its original battery capacity when traveling an average of 200,000 miles (about 320,000 kilometers). For every 20,000 miles (about 32,000 kilometers) you travel, the average battery life is reduced by 1%. According to reports, Tesla's battery first deteriorated rapidly and then stabilized. The 200,000 miles (about 320,000 kilometers) mileage is the average mileage in the United States from buying a new car to scrapped. Europe travels an average of 150,000 miles (about 240,000 kilometers) before scrapping.
test proves that Tesla owners can operate their vehicles without worrying about battery life. So in fact, users don’t have to worry too much about their battery health. Because even if you drive more than 320,000 kilometers, the battery attenuation is only about 10%. And there is no need to worry about the adverse effects of fast charging on the battery.
